THE STRETCHING PROCESS

TENAX has developed and patented an exclusive mono-axial and bi-axial stretching process for plastic netting, which can orientate the polymer molecules in a regular fashion and provide leading-edge products in terms of physical and mechanical characteristics as well as performance. Even the lightest nettings, which can reach a weight under 5 g/m2, show an exceptional tensile strength and are fully recyclable.

TENAX is a leading international group of company, based in North italy, which manufactures extruded and stretched nets, through the extrusion of thermoplastic polymers.

Support & reinforcement

tENAX extruded bi-oriented (bi-axially stretched) nets have many applications as reinforcement in the production of industrial fabrics, laminar composites, plastic, paper and for the structural support of polyurethane seats for cars, trains and planes.

unlike woven structures, extruded bi-oriented nets have the clear advantage of being ladder-proof and maintain high dimensional stability throughout the production process. this enables to obtain products whose physical-mechanical characteristics are the ideal complement to fabric, wrap or paper.

the molecular orientation process enables to achieve uniform mechanical characteristics, even on nets that exceed 4 meters in width, so that the performance of the finished product is remarkably increased. Bioriented nets are produced with weights and meshes suitable for any application.

Flow media for composite industry

tENAX provides with smart solutions for infusion in the composite industry. Dual-flat rhomboidal meshes show a great effectiveness if used as flow media during the vacuum assisted resin infusion (VAri). these kind products, belonging to the so-called oS family, can be made of high-density polyethylene, polypropylene and polyamide, according to the temperature resistance and chemical compatibility required.the usual layer-configuration of a composites mold includes the following items: the reinforcement fibers, the “peel ply” (to help the adhesion and the after-work separation), the flow media mesh and the bagging film with the nozzle to inject the resin. once the air inside the bag is sucked, the epoxy constituent can flow inside. thanks to the channels created by the grid, the fluid manages to reach any field of the composite surface with no risk of inconsistency or voids in the final product.the usage of this kind of grids allows the uniform distribution of mechanical and geometrical features throughout the mold and maintains the flow speed under control.the so-manufactured composites are suitable as wind blades, light plane wings, boat hulls and all the applications, which reaches a high mechanical stress rate.

Sod reinforcement net

outstandingly strong and versatile, rADiX, developed by tENAX, is made to optimize the production of turf rolls. its specific mesh shape let the roots grow through and make a thicker sod in a shorter time. this allows more harvestings per year and decreases the risk of waste during collection.tENAX rADiX is an extruded net made of polypropylene specially conceived to increase the productivity and the quality of sod. this bi-oriented (stretched) product is extremely light ( just 7 g/m2) but at the same time very strong.tENAX rADiX must be simply unrolled on the ground before sowing. A thin layer of soil is then laid over. the growing process will start soon. As the seedlings germinate and the roots grow, rhizomes intertwine with the netting to build a stronger structure. this allows early harvesting and stronger sods. there’s a new innovative solution for turf Growers, tENAX rADiX oXo, which offers all the advantages of a polypropylene netting without the disadvantages of the long-lasting presence of plastic under the ground after installation. tENAX rADiX oXo (oXo-degradable) has been studied to start the degradation process in 10 to 24 months depending on environmental factors.

Packaging & Protection

tENAX tp nets are designed to protect items against collision and damage caused by contact rubbing, events that often take place during handling and storage in the warehouse or during the shipment of parts packaged without protection.

tENAX tp nets are polyethylene tubular nets recommended for the protection of semi-finished mechanical parts with high finishing and precision, items with painted, galvanized, electropolished or zinc-plated surfaces.

We have specifically designed two different types:- ELAStic: elastic nets that adapt perfectly to the most irregular forms- protEctiVE: a wide range of protective nets, against any risk

the fact that the nets can be used several times reduces the production of rejects and decreases costs.

Compostable nets & environment

Nettings for food industry

tENAX manufactures through its extrusion technology nettings and grids made of compostable polymers.our light elastic sleeves, made of a raw material coming from corn starch, show good mechanical and elastic properties, are incinerable and, most of all, are environmental friendly. they were mainly conceived as a non-polluting packaging unit, but they find nowadays applications in many industrial sectors too.our knowledge allows us to extend the range of these compostable articles to protective grids, support nettings and thicker sleeves. tENAX strongly believes in the future of bio-plastics and welcomes any new requests of product development on this field.
